APPARATUS FOR HANDLING LIFE-BOATS.

Specification of Letters Patent.

Patented Feb. 16, 1915.

Application filed April 11, 1913. Serial No. 760,347.

To all whom it may concern Be it known that I, HARRY W. BROADY, acitizen of the United States, and a resident of Bayside, borough ofQueens, county of Queens, and State of New York, have in- Vented certainnew and useful Improvements in Apparatus for Handling Life- Boats, ofwhich the following is a specification.

This invention relates to improvements in apparatus for handlinglifeboats.

By the use of my invention I provide, in in one machine, suitablycontrolled and driven means for lowering or raising a lifeboat withrelation to the davits, and means for adjusting the length of the fallsat opposite ends of the boat to retain the boat in a true horizontalposition during lowering or hoisting. Furthermore, I am enabled by myimproved device to adjust the lengths of the running falls incontradistinction to adjusting the standing falls, and by combining inone machine such fall-adjusting means with the hoisting, lowering andcontrolling means, the necessary apparatus is rendered more compact,thus saving valuable deck space; a less number of sheaves, less rope,and less machinery will be required, thus considerably decreasing thecost of the apparatus; the hoisting, lowering, controlling and adjustingis centralized and may be done by one man. Furthermore, by my improvedbalancing arrangement of fall-adjusting means, the length of rope whichis paid out from one drum is taken up by the other, so that duringadjustment, the boat is moved around an axis passing through itstransverse center line; the power required to lift one end of the boatis compensated for by the paying out of the falls attached to theopposite end of the boat and substantially no power is required for suchadjustment except to overcome the bearing friction.

In the accompanying drawings, in which similar reference charactersdesignate corresponding parts throughout the several views, F'gure 1 isa side elevation of a boat suspended from a pair of'davits by suitablefalls, the running falls at opposite ends of the boat being connected tomy improved hoisting, lowering and adjusting device; Fig. 2 is anenlarged side elevation of my preferred form of combined hoisting,lowering and adjusting device; Fig. 3 is a section on line 33 of Fig. 2;Fig. 4; is an enlarged detail of the clutch illustrated in Figs. 2- and3 in uncoupled position; Fig. 5 is an enlarged detail similar to Fig. tof the said clutch in coupled position; Fig. 6 is a side elevation of amodified form of device; Fig. 7 is an end elevation of the deviceillustrated in Fig. 6; Fig. 8 is a plan view of the device illustratedin Figs. 6 and 7 Referring now to the accompanying drawings, 11 indicatea pair of davits fromwhich is suspended a boat 2 by means of falls 33%the running part of the fall 3 being led directly down to one of a pairof guiding or leading sheaves H and the running part of the fall 3' islead over auxiliary guiding sheaves 3 -3 to the opposite member of thesaid pair of guiding or leading sheaves 1- 1:. The ends of such runningparts are then connected to a pair of winding drums 5-5 mounted on acommon shaft 6 keyed to and supported in eccentric bearings 7-7 theeccentric bearings being in turn mounted in bearing standards 8-8 onframe 9, which is secured to the deck of the vessel in any suit ableposition. Suitable means for controlling or rotating and braking saiddrums 55 is provided and, as shown, an intermediate controlling wheel10, mounted on shaft 6, is provided with a series of peripheral groovesand projections 10 -10 ,pyramidal in cross-section, which projectionsand grooves, upon the shifting of the controlling wheel laterally in onedirection, frictionally engage and intermesh with similar peripheralprojections and grooves on a driving wheel 11, rotated from any suitablesource of power, not shown, and located at one side of said wheel; andupon the shifting of said controlling wheel 10 in the opposite direction, such peripheral grooves and projections 10 l0 will intermesh andfrictionally engage with similar recesses and projections in a brakeshoe 12 located at the other side of said controlling wheel 10, a lever6 cooperating with the eccentrics 7-7 being employed to shift the shaft6 and with it said intermediate controlling wheel 10 alternately intoengagement with the driving wheel and brake shoe as desired. If thedrums and controlling wheel are suitably locked or connected togetherand journaled on the shaft 6 so as always to move in the same direction,a very efiicient hoisting and v lowering control is produced, and onethat,

is peculiarly adaptable for use in my combined adjusting and hoistingand lowering apparatus. According to my invention, how ever, drums 5 and5 not only have the function of hoistingand lowering druins but alsohave theadditional function of adjusting the length of the fallsconnected to opposite ends of the boat.

In order to produce the best form of fall adjusting device the length offallspaid out at one side of the boat should be taken up at the otherside so that the boat will move around an axis passing through itstransverse center line and the power necessary to hoist the low side ofthe boat will be compensated for and balanced by the downward movementof the high end of the boat, and in the preferred embodiment of myinvention illustrated in Figs. 1 to 5, the intermediate controllingwheel 10 is loose" on the shaft 6 and has a laterally extended hub 10,the drum 5 is loose on the shaft 6 at one side of such wheel 10 and thedrum 5 is loose on said laterally extended hub 10 at'the other side ofthe intermediate controlling wheel 10, suitable bearing bushings beinginterposed'if desired between the shaft 6 and cast iron portions of thewheel 10, hub 10 and drum 5, and also between the drum 5 and theperiphery of the hub 10.

j Each of the drums 55 is provided with opposing racks 1818= and pinions14: intermeshing with the opposing racks 18-13 are carried by the wheel10, and as shown, are journaled on-pins 15 mounted contiguous to theperiphery thereof. The drums 5 and 5 are thus geared together, and,assuming that the part carrying the pinions'is stationary or retained instationary position, iffone of such drums be rotated, both will move inopposite directions, and if one of such drums be locked to theintermediate pinion carrier, or if one or more ofthe pinions be lockedagainst rotation, then the drums and pinion carrier will be compelled torotate together in the same direction for the purpose of enabling thedevice to be used interchangeably as means for hoisting or lowering andfor adjusting. In, the preferred embodiment of my invention I pro vide aclutch for locking the drum 5 to the intermediate pinion carrier orcontrolling wheel 10, comprising an integral counterpart clutch-box 16on the'hub of the drum 5*, having the usual projections and interdentalspaces, which co-acts with a slidable hub or clutch ring 17 having acounterpart box 18 with the usual projections and interdental spacescorresponding with those of the counterpart box 16 on the drum 5*. Asshown, the clutch ring 17 is keyed to the hub 10 and is shifted intoengaging and disengaging'positions by means of a rectangular link 19'pivoted intermediate its lends aslat 1 9*, connected at one end to ashoe 19 bearing on said ring 17 and having its other end forked as 21019 and embr'acing a pivoted "eccentric '20 moved by a lever 21,Obviously when the eccentric is moved around its pivot in oppositedirections, the forked link will be rocked to move the clutch box intoengaging and disengaging positions respectively, and may be locked insuch positions. Assuming now that the clutch ring 17 is' in engagingposrtion,the drums will be locked together and the apparatus may be employedto hoist or lower the boat and such hoisting and lower- 1ng maybecontrolled by alternate engage ment of the controlling wheel with thefriction drive and brake shoe. If, however, it

is desiredto employ the device to adjust the lengths of the falls, thecontrolling wheel 10 is braked,'the clutch ringl'? is moved lntodisengaged position and one of the drums rotated in one direction or theother, accordingto which end of the boat it is 'de-' sired to raise orlower. My preferred means for so rotating the drums comprises aninternal rack 22 on the side of the drum 5 opposite to that havin thisrack 22 is engage by gear 24 on shaft 25 in bearings 25 on an extension26 of the standard 8 pinion rack 23 and The operation of the devicedescribe d will be apparent from the above description and it will beseen that by the said appa 2'? has integrally cast therewith, a control?ling or driving and braking portion 27 and the drum 27 is provided witha laterally extended hub 27 on which hub is keyed a worm wheel '32 whichmeshes with a worm 33 mounted in suitable bearings on the opposing drum27 Thedrums and controlling wheelare shiftable in opposite direcl fetions by means of a lever 34: 'into alternate engagement with a drivingwheel 35 or brake shoe 36, suitably mounted on opposite,

sides of such drums. The shifting of the drums to driveand brake thesame issubstantially similar to that above described. When, however, itis desired to adjust the length of the falls the controlling wheel isthrown into engagement with the brake shoe and the Wormshaft turned inopposite directions according to Whether it is desired to raise or loWerthe end of the boat secured to the movable drum 27. Means, such as rack37 and pinion 38 mounted on shaft 39, is preferably provided to take upslack.
